As a Texan, my biggest problem with TexMex/Mexican food in South Florida is it is hard to find any authentic offerings. I think this is because almost everyone that lives here is from somewhere else and they complain so much that it forces establishments to lessen the spice/heat in their food.
Why is this a problem only for the TexMex category? You wouldn't go to an Indian restaurant and ask them to hold the chilies in the curry (If you do this, I'm sorry you are high-maintenance). El Camino Tequila Bar in Delray doesn't give in to the pressure. They don't water down all the wonderful Mexican flavors like most restaurants in South Florida. They do give you a "heat warning" when you order something spicy.
When you dine-in on Tuesdays they offer all their gourmet tacos for only $2 each. Such a deal when you realize all the effort they put into their authentic sauces. Also, you if you can manage to squeeze into the bar area they have a very reasonable happy hour.
The reason I asked my boss to not to work on Tuesdays at WPTV.com is because my friend Heather and I love to go and get our tacos and pair them with a Watermelon-Jalapeno Margarita, Guacamole, and salsa, and wash it down with a Modelo Especial.
